Baker was a multiple junior world champion in 2011-2012, and made her elite World Championships debut in 2016, where she finished fifth in the team pursuit and was just one final sprint win away from the podium in the points race.
Those results booked Baker a spot to her first Olympic Games, however a training crash on the eve of the Rio 2016 Games cruelled Australia's chances of a podium finish in Rio. Gallantly, Baker lined up in all three of the team’s rides as the team eventually defeated Italy to claim fifth.
